Any other ways I can make a model more visible?

As I posted in another thread, I have a set of models that I use for roofing materials in one of my maps. Trouble is, while I can see the models in the editor just fine, in some of the shots they don't show up in-game. I've tried changing the minimum and maximum extents of the model to very large (or large negative) values, but this doesn't seem to get me very far (although it appears to have helped a little bit).

Is there anything else I can do to the models for this roofing material to ensure that they are visible in-game?

Use smaller 'bricks'.

Alternitively, you can try making sure that the roof models are 100% scale, scaling doodads in the WE causes clipping issues, but i -think- if they're originally that large then you don't get those issues.

Try basing it on the world tree. Something must be right about that. If not, I can scale up those roof models.

Did you change the extents in both the model info area and each sequence? And the boundsradius?

Magos' editor work just as fine, and it's faster. It lets you even skip the convertion part.
